Waist Liposuction: Waist Liposuction can reduce localized fat accumulation alone to achieve curvaceous effect, and can also reduce abdominal sagging. Moreover, on the basis of not damaging blood vessels and nerves, it can enhance the elasticity and luster of the skin, leaving no scars after the operation, with obvious shaping effect. At present, waist liposuction has become one of the most performed plastic surgery in the world and in China, and the technology has been relatively mature and stable. Waist liposuction usually adopts ultrasonic liposuction and electronic liposuction method. Applicable people: aged 18 to 55 years old, no organic cardiopulmonary disease, no history of severe drug allergies, no thrombophlebitis, no coagulation disorders of the waist fat accumulation of people, feasible liposuction. Liposuction should not be performed during pregnancy, so as not to affect the fetus; for obese children, children and adolescents are in the stage of growth and development, if the surgery interferes with the normal development of fat in the body, it will affect the level of hormone metabolism in the body, thus interfering with the normal growth and development, so liposuction is best to be considered after the age of 18 years old. Postoperative precautions: 1. In the early postoperative period, you can carry out light daily activities and physical labor; 2. As part of the swelling fluid remains under the skin, there may be more oozing fluid on the day of operation. If penetrate the dressing, you can use sterile gauze or clean toilet paper outside the dressing, don’t open the dressing by yourself to avoid contamination of the wound; 3, you can’t take a bath for 3 to 5 days after the operation to avoid contamination of the wound; 4, you can continue to wear tight elastic clothing after the operation and adjust the pressure of the elastic clothing at any time according to the local situation. Abdominal liposuction: abdominal liposuction, is the deep subcutaneous fat suction, while leaving the superficial fat immediately adjacent to the surface of the skin about 1cm thick, so that the local fat layer becomes very thin, the belly disappeared, and is not easy to rebound after surgery. Possible complications: 1. Bleeding. Postoperative petechial hemorrhage under the skin, which is caused by the rupture of capillaries during suction, and can generally subside within two weeks. 2.Oedema. Due to tissue damage and subcutaneous residual part of the swelling fluid, so that the suction site edema, generally subside faster. 3, uneven. It is more common in the early stage, and it will be changed slowly after pressurization and shaping. 4.Subcutaneous nodules. After the operation, some hard knots can be touched or the whole suction site becomes hard, which is due to the formation of inflammatory nodules or hematoma formed by subcutaneous tissue damage, fat liquefaction, generally within 3 months can be slowly absorbed and become softer. Surgical points: 1, the choice of incision: the choice of incision should be convenient for suction operation and hidden, abdominal incision should be selected in the umbilicus or above the pubic symphysis. The original surgical incision on the body surface (such as appendiceal incision, cesarean section incision) can also be utilized. The length of the incision is 1~2cm, which is suitable for inserting the suction tube, too long will affect the effect of negative pressure and leave a long incision scar, which affects the aesthetics. 2, surgical operation: according to the design of the incision to cut the skin, subcutaneous tissue, with scissors in the subcutaneous fat layer slightly separated, the right hand holding the suction head handle will be inserted into the suction site, and then turn on the electric suction, so that the negative pressure reaches 66.5 ~ 93.1kPa (500 ~ 700mmHg) can be in accordance with the scope of the marking of the zipper scraping suction. During the operation, the lateral hole of the suction head generally faces to the deep side or the side, and the left hand strokes the skin surface of the suction site or lifts the suction tube together with the subcutaneous fat to grasp the depth of the operation and the amount of suction, and at this time, the light yellow adipose tissues can be seen to be suctioned out through the transparent connecting tube; with the operation, the suction material can be changed into the red color with a small amount of blood until the blood-like purplish-red color, and at this time, the site should be stopped to stop suctioning, and in the case of no negative pressure, the suction can be performed. Without negative pressure, the suction head will be pulled out; if the suction range is large, the original incision can be designed as the center of another several small incisions, radial tunneling suction, so that the tunnel suction through the incision crosses the residual subcutaneous tissue in the form of a honeycomb, which not only reduces the bleeding, but also reduces the unevenness of the surface of the skin after the operation. 3.Drainage：After the operation is completed, one or several silicone tubes are placed into the incision according to the size of the suction area in order to connect the negative pressure drainage bottle for drainage after the operation. 4, bandage: bandage is the final step of liposuction surgery, the effect of liposuction surgery is crucial. The incision is covered with sterile gauze, and sterile cotton pads or sponges are evenly placed on the surface of the whole suction area, covered with special elastic compression garment or elastic sleeve. Contraindication: Morbid obesity secondary to other diseases does not belong to the treatment scope of liposuction; poor general condition or poor function of major organs such as heart, liver, lungs, kidneys, etc.; immature adolescents; abnormal coagulation mechanism and women in menstruation should be prohibited to do liposuction. Postoperative precautions: 1, short-term ban on seafood and spicy food after surgery; 2, do not stay in bed after surgery, you can carry out light daily activities and work, which will help to reduce swelling as soon as possible and reduce the chances of fat embolism; 3, if the surgical site of the skin unevenness, you can carry out a gentle massage, usually about half a year later will be flat, if after half a year is still not flat, then you need to go to the hospital for medical treatment. Special tips: 1, the postoperative effect should be rational: the effect of liposuction, you can use your hands to grasp the abdominal fat, the general thickness of about 1cm belongs to the more normal, so that the candidate can predict the effect of the surgery can be improved. If severe obesity, may be more than 1cm, but not that the operation is not successful. 2, special circumstances require a combination of multiple surgeries: generally speaking, if a woman gives birth twice in close proximity, most of the peritoneum has a significant slackening phenomenon. At this time, in addition to liposuction surgery can also receive a tummy tuck surgery, can more quickly restore the slim waist and smooth skin. 3, liposuction instrument good or bad directly affect the effect of liposuction: liposuction instrument variety, liposuction effect is good or bad, the key lies in the performance of the liposuction instrument and the doctor’s technology. Buttock liposuction: Buttock is composed of a large amount of muscle and fat from the sacroiliac bone and the upper end of the femur, and the proportion of fat is often very large. Liposuction of buttocks focuses on reducing the circumference of buttocks, trimming and lifting up the loose and sagging part, narrowing the width of the circumference of buttocks, adjusting the height of the buttocks backward appropriately, and reducing the fat on the upper buttocks, so as to make the curves from waist to buttocks sleek and smooth. At the same time, excess fat at the root of the thighs can also be removed, making the thighs look beautiful and slender. Liposuction for different buttock shapes: drop buttocks should be suctioned to remove part of the fat in the lower part of the buttocks, so that the lower part of the buttocks is spherical, and the buttock cleavage will be revealed; hulk buttocks should be suctioned to remove the subcutaneous fat in the outer buttock area and the connection of the lateral waist, so that the upper part of the buttocks is spherical, and the shape of the buttocks and waist curves will be shaped; fat buttocks should be suctioned to reduce the whole buttock area and the buttock circumference is narrowed down to the range that is suitable for the height of the buttock; deflated buttocks should be considered to be autologous fat transplantation or other tissue substitutes to augment the buttock area. Consider autologous fat grafting or other tissue substitutes for buttock augmentation. Liposuction procedure: Liposuction of the buttocks is performed in the crease of the buttocks and thighs by making two small 5mm incisions to symmetrically and evenly suction the fat. For the places adjacent to the waist and thighs, special attention should also be paid to deal with the transition surface, so that the post-operative hip curve is natural and smooth. After the recovery of the surgical site, the traces of the incision will disappear into the skin folds and will not be easily detected. Contraindications: 1, morbid obesity caused by other diseases secondary to other diseases, does not belong to the scope of treatment of liposuction; 2, poor general condition or the main organs such as the heart, liver, lungs, kidneys and other dysfunctions should not be done; 3, is not suitable for underdeveloped adolescents; 4, abnormal coagulation mechanism and is in the menstruation period of the female, should be prohibited to do liposuction; 5, excessive abdominal contents, subcutaneous fat less people should not be performed Liposuction of the buttocks for weight loss. The anatomical feature of buttocks is that the fat layer is extremely thick, which can be divided into superficial layer (honeycomb layer) and deep layer (platysma layer), therefore, when liposuction is carried out, it is necessary to suction both superficial and deep fat, i.e., full-layer liposuction, in order to get a better contouring; During the operation, attention should be paid to the direction of the liposuction needle, and the suction area should be far away from the penetration point of sebaceous blood vessels, so as not to hurt the important structures easily; Attention should be paid to symmetry of the two sides, and the amount of symmetrical position suction should be taken into consideration; the amount of symmetrical position suction should be taken into consideration. Symmetry, symmetrical position should be the same amount of suction. Postoperative precautions: 1, the recovery period after the operation is 2 to 3 days, the surgical site may appear bruising and swelling, and it will take about 1 month for the swelling to go down and become natural again; 2, the bandage should be used for 1 to 2 days after the operation, and after that, a compression garment should be worn; 3, bed rest should be used for 5 days after the operation, and more vegetables should be eaten in the 2 weeks after the operation to prevent constipation, antibiotics can be used when necessary; 4, the stitches should be removed in the 2 weeks after the operation, and intense exercise should be prohibited in the month, and elasticity should be used in the 3 months after the operation. The stitches will be removed 2 weeks after the operation, prohibit intense exercise for 1 month, and use elastic bandage for 3 months for compression and fixation. Liposuction of arm: Liposuction of arm is to open a small opening in the armpit, the fat of the back side of the upper arm and shoulder will be suctioned out in layers and evenly. The procedure is usually performed under local anesthesia, or general anesthesia can be chosen depending on the candidate’s specific situation. For normal human body, arm liposuction does not change the body’s energy metabolism balance, the metabolic rate does not increase, so there will be no regeneration of adipose tissue. Surgical points: 1, according to the body shape of the marked liposuction parts and key areas: liposuction of the upper arm should be preceded by contouring design, the design of the candidate standing, shoulder abduction 90 °, elbow flexion 90 °; the doctor observes the degree of sagging skin in the middle 1 / 3 of the back of the upper arm of the candidate, the thickness of the adipose tissue with a pinch test to determine the liposuction range of arm liposuction; the thin skin of the medial side of the general do not have to be pumped, and only pumped the front outer and posterior outer; with the gentian test, the thickness of fat tissues to determine the range of arm liposuction. Only the anterolateral and posterolateral sides should be suctioned; the scope of suction and key suction areas should be marked with gentian violet, and the deltoid muscle area, armpit and lateral chest and back around the shoulder joint, which have an influence on the shape of the upper arm, should also be marked for simultaneous suction correction. 2, the marked range of uniform injection of lipolytic solution: arm liposuction generally let the candidate to adopt the prone position, two arms outward. In order to make the incision inconspicuous, the needle is used close to the ulnar eagle’s beak, which can meet the liposuction needs of the anterolateral, posterolateral, and deltoid regions of the upper arm. 3.Suction of excess fat out of the body under negative pressure, shaping while suctioning: after anesthesia and swelling in the marked area, suction is performed in a fan shape from deep to shallow, mainly in the posterior lateral upper arm and deltoid muscle area for full-layer suction (shallow and deep), and the middle part of the upper arm should not be over-suctioned in order to avoid concavity and convexity. 4. Thin fat, use a thin needle to suction: the amount of fat in the arm is generally small, mostly superficial fat, suction should be fine, accurate operation, with a thin needle (with a 2.5mm diameter minimally invasive needle) suction, in order to have a good suction effect. Common side effects of arm liposuction: 1, skin unevenness, asymmetry, insufficient suction, erythema; 2, hematoma, skin laxity and sagging, infection, peripheral tissue damage, fat embolism. Liposuction of legs: Liposuction of legs is usually performed on thighs and knees. The fat of the thigh and its upper dermis are thinner, so it is easy to have unevenness when suctioning, and the operation is relatively more difficult. Liposuction of different leg shapes: liposuction of the legs should be combined with the characteristics of my temperament, combined with the thickness of the buttocks and calves, to choose the appropriate form; buttocks are not big, calves thin people, you can reveal the thigh muscles vaguely visible, to give a person the feeling of robust and powerful; buttocks are large, the calves are thick people, you need to retain a moderate amount of fat, so that the proportion of the buttocks and calves more coordinated. Surgical points: 1, the incision should be hidden in the groin, inside and outside the knee, after the buttocks; 2, thigh liposuction due to the large area of more general anesthesia, calf liposuction usually local anesthesia can be; 3, lipolytic solution will be injected into the liposuction site, so that the liposuction process is smoother, and at the same time, reduce the amount of bleeding. Applicable people: people under 55 years old without organic cardiopulmonary diseases, no history of serious drug allergy, no thrombophlebitis, no blood clotting disorders, and excessive leg fat during non-pregnancy. Postoperative precautions: 1, 1 month after the operation, adhere to the “do not stand if you can sit” and “elevate your feet when you are not doing anything”, which can effectively reduce the tension of the wound and avoid swelling at the same time; 2, when replacing the cosmetic adhesive tape, clean it with saline or cold boiled water, and then re-paste it, and change it once in 3 days. In order to speed up the recovery after liposuction, proper leg massage can be performed; 4. If the wound has entered the recovery period without secretion, the wound can be treated as a scar for care. In the first month, the cosmetic adhesive tape can be put on to reduce tension and avoid protrusion and widening; in the second month, whitening care products (containing levulinic acid or andrographolide) can be applied to minimize the pigmentation.
